From a4d8215ebba6009fc4b17ef7b61ff51238f0f404 Mon Sep 17 00:00:00 2001 From: Anshul Gangwar Date: Thu, 9 Oct 2014 10:37:21 +0530 Subject: [PATCH] CLOUDSTACK-7688, CLOUDSTACK-7747: restricted various operations for VM with VM snapshots which breaks VM snapshots. Now they are informed that they cannot perform the operation. To perform operation they have to remove VM snapshots of VM. --- .../cloud/storage/VolumeApiServiceImpl.java | 22 +++++- .../src/com/cloud/vm/UserVmManagerImpl.java | 77 +++++++++++-------- .../vm/snapshot/VMSnapshotManagerImpl.java | 12 +++ 3 files changed, 78 insertions(+), 33 deletions(-) diff --git a/server/src/com/cloud/storage/VolumeApiServiceImpl.java b/server/src/com/cloud/storage/VolumeApiServiceImpl.java index b70d753ac44..07f62c36232 100644 --- a/server/src/com/cloud/storage/VolumeApiServiceImpl.java +++ b/server/src/com/cloud/storage/VolumeApiServiceImpl.java @@ -707,6 +707,13 @@ public class VolumeApiServiceImpl extends ManagerBase implements VolumeApiServic /* Does the caller have authority to act on this volume? */ _accountMgr.checkAccess(CallContext.current().getCallingAccount(), null, true, volume);
